Jumping Amp Gauge After MSD Install
Yeah I wanted to get rid of the ballast resister but I couldn't find a switch 12v source that kept at least 9v when cranking except for the old coil +. This is obsessively after the resister.
So consent 12v is right to the battery positive.
Ground is on a post on the firewall
Currently using the White wire for points trigger (will switch to mag pick-up when I change engines)
Switched 12v from old coil + (blue factory wire)
